(this post is made operating under the assumption that the friend wants to run one subwoofer off of its own amplifier from what I can gather from your post)

Does the buddy have enough electrical system in his Maxima to run two 1,000 watt amplifiers? That would be the first thing that needs to be addressed, in my opinion, before deciding what voice coil configuration drivers to purchase.

Outside of that, however, he'll need to figure out at what impedence does the amp or amps to be used make the power he wants to put into each subwoofer? (most likely either 2 Ohms or 1 Ohm)
If he wants to run each subwoofer at 2 Ohms then he'll want to buy the dual 4 ohm version.
To run each subwoofer at 1 Ohm he'll want the dual 2 ohm version.

In either case he'll want to wire the coils on each driver in parallel like so:
